2004 Alero's

Will parts that say their from the years 1999-2002 work on my 2004 model. like this Dhp Pcm thing

Grand AM GT w/3400 : 1999 - 2002

will that work on my 2004? same with every thing else. I"M SO CONFUSED!!!

some things will fit but that pcm, im not sure about connections wise if its different but i can tell you the programming differs from year to year and you cant use one from a grand am cuz the shift points are different than ours because their tranny's gearing is a little different........

just email dhp and tell them what you want and what kinda car you have and they will set you up.......

You gotta email dhp about the pcm. It has to be programed for the ALero. The GA one will not work.

Most parts will fit all years of the 3400 motor, but the 2.4 and the 2.2 are total different. All non motor stuff will fit (wheels, headlights, gauges, etc)

BTW do you work for Pepsi too?

alright cool thanks guys


No, Just a pepsi fan. Mmmmmmm

almost every year gm makes changes to the computer.
in 03 or 04 they changed the cam sensor and prolly some other things so you would have to see if they can do a tune for an 04

darn i am looking for a pepsi distrubtor to sell me some 5gallon bib

Transmission control, well how the trans knows were the shifter is, is different for '04 compared to all other years, so a computer for something older than an '04 (i.e. '99-'03) will not work if you have an automatic trans. That is a for sure thing, don't even try it.
